This invention relates to wood trimming or edging machines and more particularly to machines for severing the rough edges from objects, such as barrel staves.

An object of the invention is to provide a machine of this type wherein a plurality of superimposed barrel staves or other flat longitudinal members may be trimmed along their edges in a single operation.

Further the invention provides means whereby the completed staves are caused to fall upon a chute from whence they are discharged into a suitable receptacle placed to one side of the machine.

The inventionalso contemplates a stave trimmer whereby the staves may be expeditiously trimmed, is safe to operate and can be operated by an unskilled workman.

With the preceding and other objects and advantages in mind, the invention consists in the novel combination of elements, constructions and arrangements of parts to be hereinafter specifically referred to, claimed and illustrated in the accompanying drawing,

, wherein,

Figure 1 is an end elevation of the invention;

same;

Figure 3 is a front elevatlon; Figure 4 is a top plan view, and

Figure 5 is a horizontal section taken on line 55 of Figure 3. V 7

Referring to the invention in detail a cast metal frame 5 embodying supporting legs 6 from which vertical standards 7 arise and are connected together by horizontally extending T beams, is provided.

At their upper ends these standards are formed with a pair of horizontally aligned arms 8 in which a shaft 9 is journaled, the latter carrying a large pinion 10 which is engaged by a drive pinion 11 fixed to a drive shaft 12 journaled in bearings 13 secured to the inner ends of the arms. A drive pulley 14: engaged by a drive belt 15 driven from an suitable source of power is fixed to the drive shaft at one end. A fly wheel 16 is also fixed to rotate with the drive shaft.

Parallel upstanding knives 17 are arranged Figure 2 is a vertical sectional view of the belowthe shaft 9for trimming the longitudi- I nal edges of superimposed barrel staves, the

former being securedwithin'a rectangular horizontally disposed frame v18 which is mounted; upon horizontal brackets or extensions 19 projecting laterally from the standards at their lower ends. V

As'illustrated in Figure 2 theseknives have their cutting edges disposed'abo've the frame and each is detachablyheld by'fastenings20; ,An' angularly'disposed chute or apron 21 is secured to the under face of thebrackets or extensions with'one end projecting -beyond the frame 5 to catchand discharge the staves to one side of the machine as-they fall thru the frame 18 after the cutting operation.

-A pair of'reciprocable rods 22 carrying heads 23 at their lower ends are mounted in guides 24 projecting forwardly from the standards. These heads are located in vertical alignment with the knives at the ends thereof to engage the ends of a number of superimposed staves resting upon the knives.

To press the heads against the knives to:

sever or trim the rough longitudinal edges therefrom connecting rods 25 eccentrically' mounted upon the shaft9 are pivotally connected as at 26 to the reciprocable rods22.

18O driven shaft 9 a clutchmember 27 adapted to engage a co-acting clutch member 28 fixed to the gear 10 is keyed to the shaft9.

In order to control the operation of the For the purpose of actuating the clutch member 27 a shifting arm 29 is pivotally attached as at 9.9 to one of the vertical standards to swing about a horizontal axis and is operatively connected with a hand lever 30 by a rod 31. The upper end of this arm is beveled as at 32 to engage between spaced lugs 33 on the clutch member 27 to shift the latter into engagement with the clutch member28 'u'pon rocking the hand lever in one direction.

Vertical bars or gaugeelements 34 are sup y ported rearwardly 'of the knives against which the stacked staves contact to correctly position the latter with respect to the knives. fl

I claim gas I 1. In a stave trimming machine, a pair of parallel uprights, horizontally aligned extensions projecting therefrom, a pair of spaced knivessupported from the extensions upon I 5 which a plurality of stavesis adapted to be superimposed, iorwardly projecting arms carriediby the standards above the knives, verftically disposed gage bars depending from the arms and extending to a point to one side 0 -of'-one'-"-of theknives and against which the staves are adapted-to be placed whereby they Will be correctly'positioned on the knives tubular guides carried by thearms' directly above the knives, a reciprocable rod; movable in each guide, and a head carried by each .rodgfonpressing the; staves against the knives .totrimthe edges of the latter.

In a stave trimming-machine, a pair of iparallel'uprights, horizontally aligned extenv sions-projecting'therefrom, a :pair of spaced kniyes;,supported jfrom the" extensions upon which the staves areradaptedito'be superimposed,forwardlyprojecting arms carried by the standards above the knives, tnbular guides r1 carried;by-thearms directlyabove the knives,

eareci-procable rod movablein each guide-and :a-headfcarried byeach rod for pressing'the staves against the knives. 1
